PISTON FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent. Patented June 14, 1921.

Application filed June 27, 1919. Serial No. 307,102.

To all whom it may concern:

citizen of the United States, residing at 1728 Connor Ave, in the city of Joplin, in the county of Jasper, in the State of Missouri, have invented new and useful Improvements in Pistons for Internal-Combustion Engines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in pistons for internal combustion engines, in which the piston is made of three sections secured together by bolts or screws in such manner as to admit of adjustment.

The objects of my invention are: first, to eliminate piston slap, a noise familiar to those versed in engines, without using a new piston; second, to produce a piston that will wear longer; third, to make an adjustable piston;

In the drawing, A represents the main section of the piston B represents two similar interchangeable detachable sections secured to the main section A by bolts on screws which are designated by the letter C. The

bolts pass through the detachable sections B and through openings in a web A, carried by the main section of'the piston. These bolts or screws are recessed within the circumference of the piston as shown in the drawing. The dotted circle E indicates the location of the piston pin. Sections B of this piston are shown as joined to section A in planes that pass through the piston pin. This piston is cylinder shaped.

In my invention due consideration has been given to simplicity of design and low production cost. After adjoining edges of the above mentioned sections of this piston have been machined the sections are then secured together in the manner shown in drawing and the piston is then finished as a single piece. This piston is reamed for the piston pin and grooved for a plurality of rings.

The piston of an internal combustion engine wears most upon the surfaces represented by the extreme rights and left of the drawing, and decreases to the minimum toward the part of the piston represented by the center of the drawing. In my invention this wear is eliminated by inserting metal shims between the main section A and the two detachable sections designated by the letter B.

I claim A piston comprising a cylindrical portion forming a piston head, a web projecting therefrom and extending throughout the length of the piston, the width of the web being substantially equal to the diameter of said cylindrical portion, said web being of substantially uniform thickness throughout, a pair of substantially semi-cylindrical members arranged on each side of said web and forming the body portion ofthe piston, said web and said semi-cylindrical members being provided with registering openings, and

bolts arranged in said openings to retain said semi-cylindrical members in position. GEORGE S. FOWLER.
